• Model-year pro­duction: 20,479.
• Calendar-year sales: 19,819.
• The 1,000,000th Corvette was produced on July 2,1992.
• It was a 1992 Corvette convertible and was posed for a factory publicity photograph alongside a first-year 1953 Corvette.
• With the introduction of the base LT1 V-8, the introduction of an Acceleration Slip Regulation (ASR) traction-control system as stan­dard equipment and the standard use of Goodyear Eagle GS-C high-performance tires with directional and asymmetrical tread design, Chevrolet Motor Division could advertise that "The all-around performance of the Corvette has been raised to the highest point in the car's 39-year history."
• Eight major factors contributed to the increased power of the LT1 engine:
  1. A reverse-flow cooling system
  2. Computer-controlled ignition timing
  3. A low-restriction exhaust system incorporating a two-piece converter and exhaust-runner assembly for easier service access
  4. The use of high-compression-ratio pistons
  5. The use of a new camshaft profile
  6. The use of new free-flowing cylinder heads
  7. The use of four-bolt main bearing caps on the three center bear­ings
  8. The use of new synthetic SW-30 engine oil (also eliminating the need for a separate engine­oil cooler).
• An LT1-powered Corvette with automatic transmission was tested for 0-to-60 mph in 5.26 sec­onds and did the quarter mile in 13.9 seconds at 102.2 mph.
• An LT1-powered Corvette with the six-speed manual transmission was tested for 0-to-60 mph in 4.92 seconds and did the quarter mile in 13.7 seconds at 103.5 mph.
• A 1992 Corvette ZR-1 with standard manual transmission was tested for 0-to-60 mph in 4.3 seconds and did the quarter mile in 12.9 seconds.
• This proved that the LT1 engine had dra­matically narrowed the performance gap between the base Corvette and the much more expensive ZR-1 Corvette.
• On August 28, 1992, Chevrolet Motor Division announced that David McLellan would be retiring as Corvette chief engineer.
• McLellan had taken over the Corvette program after the retirement of Zora Arkus-Duntov in 1975.
• Chevy's assistant manager of public relations Tom Hoxie said in 1992, "During McLellan's 18-year tenure he transformed the Corvette from an American muscle car into an internationally-acclaimed, high-performance sports car that runs rings around a host of more expensive European and Japanese models."
• Said McLellan, "I can't think of a better time for me to be leaving.
• No manufacturer has ever built one million sports cars and at the age of 40 the Corvette is stronger than it's ever been. Our all-new car is a few years old and it's time to let some­one else put their stamp on it."
